Four Cups of Coffee A Day Cuts Risk of Oral Cancer

An anonymous reader writes "Coffee may help lower the risk of developing oral and pharyngeal cancer and of dying from the disease. The study, published in the American Journal of Epidemiology, was conducted using the Cancer Prevention Study II. The large cohort study began in 1982 by the American Cancer Society. Researchers were able to examine 968,432 men and women, none of whom had cancer at the time of their enrollment in the study." Four or more cups a day lowered the risk of getting oral cancers by a whopping 49%.

mmmm

Sure because the people who drank more than 4 cups a day died of other "natural" causes like a tac a cardia, its a blip but it could have been caused by a few other behavioral coincidences. It feels a little more like someone trying to get value out of 26 years of possibly unfruitful research. there's another study that show's no determinable link! http://cancerres.aacrjournals.org/content/49/4/1049.short [aacrjournals.org]

but certainly you can't disprove something by showing no determinable results on it.

If 100 out of 10000 non-coffee-drinkers got cancer (1%) and 51 out of 10000 coffee drinkers got cancer (0.51%) that's a 49% decrease.
